Hunter System Shows Zones Running But No Water: Check Valves & Voltage

Hunter Controller Indicates Run But No Flow: Systematic Diagnosis

Controller shows stations advancing, house water fine. Two main paths:

1. Verify Water Reaches Valves

1. Find green valve boxes in yard. 2. Manually open one valve: turn solenoid ½ turn CCW. 3. If water flows → supply is good. 4. If no water → main irrigation shutoff closed or pump issue.

2. Test Controller Output Voltage

1. Activate Zone 1 manually. 2. Multimeter: AC volts between "COM" and "1" terminals. 3. 22–26 VAC = controller good. 4. Low/zero = controller failure.

3. If Voltage Good But No Valve Action

• Common wire cut (all zones dead).
• All zone wires cut (unlikely).
• Master valve / pump start relay not energized.

Reply with voltage reading and manual valve test result for next step.
